Red nocturnal lamp

Strange, usually a 50w would at least get you in the lower preferred range. I do prefer the round bulbs to the spot bulbs and find they give you a wider area of heat. Is your room below 20C? You could get a higher wattage lamp or try a heat mat. The mat heats up to 100F and heats up part of the substrate but won't warm the air much, so you might need to use the red lamp as well but not directly above the mat until summer but the mat will definitely get your warm end temperature. Place the mat on polyeterene sheet then use rubber adhesive feet to raise the tank off it for airflow and prevent hot spots if the animal should burrow down onto it. Place the stat under the substrate right above the mat. I can send you a 60W bulb and a 7W heat mat I have spare and you could see what works best for you
